**Nome do software vulnerável e versões afetadas: Nuvoton Trusted Platform Module (NPCT75x), versões 7.2.x anteriores à 7.2.2.0 Descrição: Um invasor com acesso físico poderia extrair uma chave privada de Criptografia de Curva Elíptica (ECC) por meio de um ataque de canal lateral contra o ECDSA, devido a uma discrepância de tempo observável. Esta vulnerabilidade afeta a implementação do ECDSA devido a uma discrepância de tempo observável, permitindo que um invasor possa extrair informações confidenciais. Recomendações: Para o Nuvoton Trusted Platform Module (NPCT75x) versões 7.2.x anteriores à 7.2.2.0, atualize para a versão 7.2.2.0 ou posterior para resolver o problema. Como solução alternativa temporária, considere restringir o acesso físico ao módulo para minimizar o risco de exploração.

**Name of the Vulnerable Software and Affected Versions** Java SE versions 7u231, 8u221, 11.0.4, 13 Java SE Embedded version 8u221 **Description** The issue allows an unauthenticated attacker with network access via multiple protocols to compromise Java SE and Java SE Embedded, resulting in unauthorized read access to a subset of accessible data. This issue applies to Java deployments that load and run untrusted code and rely on the Java sandbox for security. It can also be exploited through APIs in the specified component, for example, through a web service that supplies data to the APIs. **Recommendations** For Java SE versions 7u231, 8u221, 11.0.4, 13, update to a version that includes the fix for this issue. For Java SE Embedded version 8u221, update to a version that includes the fix for this issue. As a temporary workaround, consider restricting access to the `Security` component until a patch is available. Avoid using APIs in the `Security` component to minimize the risk of exploitation, especially in scenarios where untrusted code is loaded and run.

**Name of the Vulnerable Software and Affected Versions** Infineon Trusted Platform Module (TPM) firmware versions prior to 0000000000000422 - 4.34 Infineon Trusted Platform Module (TPM) firmware versions prior to 000000000000062b - 6.43 Infineon Trusted Platform Module (TPM) firmware versions prior to 0000000000008521 - 133.33 YubiKey 4 versions prior to 4.3.5 **Description** The issue is related to the mishandling of RSA key generation in the Infineon RSA library, making it easier for attackers to defeat various cryptographic protection mechanisms via targeted attacks. This can be exploited by a remote attacker to reveal the secret part of a key. Examples of affected technologies include BitLocker with TPM 1.2, YubiKey 4 PGP key generation, and the Cached User Data encryption feature in Chrome OS. **Recommendations** For Infineon Trusted Platform Module (TPM) firmware versions prior to 0000000000000422 - 4.34, update to a version after 0000000000000422 - 4.34. For Infineon Trusted Platform Module (TPM) firmware versions prior to 000000000000062b - 6.43, update to a version after 000000000000062b - 6.43. For Infineon Trusted Platform Module (TPM) firmware versions prior to 0000000000008521 - 133.33, update to a version after 0000000000008521 - 133.33. For YubiKey 4 versions prior to 4.3.5, update to version 4.3.5 or later.
